CAR-MOVER.

Specification of Letters Patent.

Patented J an. 20, 1920.

Application filed May 3, 1918. Serial No. 232,260.

To all whom it may concern:

Be it known that I, FRANK F. STERNER, a citizen of the United States, residing at Harnedsville, in the county of Somerset, State of Pennsylvania, have invented certain new and useful Improvements in Car- Movers; and I do hereby declare the following to be a full, clear, and exact desorlption of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in car movers and particularly to devices for use in pushing mine or pit cars.

One object of the present invention is to provide a novel and improved structure of this character whereby the operator can more easily and effectively push the car and prevent the same from slipping backwardly.

Another object is to provide a novel and improved structure of devices of this character which are capable of ready and quick adjustment and attachment to different types of mine cars.

A further object is to provide a novel and improved device of this character wherein the act of pushing the car is accomplished by both the forward and rearward movements of the operating lever.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of my improved car mover in operative position.

Fig. 2 is an enlarged side elevation of the device.

Fig. 3 is a. rear elevation of the device.

Fig. 4 is a vertical sectional view taken on the line l4 of Fig. 3.

Referring particularly to the accompanying drawing, 10 represents a portion of a mine car having the end sill 11, and 12 represents the ties of the mine railway on which the car runs, and in connection with which my invention is particularly adapted for use.

A substantially U-shaped member is provided in the bight portion of which there is secured a block 13, by means of the bolt 14, said U-shaped member being designated by the character 15, and. extending transversely through the said block is a bolt 14:,

on one end of which is pivotally mounted a vertical operating lever 17. Pivotally connected to the lever above the bolt 14 is a rearwardly and downwardly extending pawl member 18, while a shorter pawl member 19 is pivotally connected to the lever below the bolt, as clearly seen in the drawing. Disposed vertically through the arms of the U- shaped member 15, outwardly of the block, is a bolt 20, said bolt having the winged nut 21 on its upper end whereby the arms of the member may be brought into firm clamping engagement with the end sill of the mine car. To further insure the proper gripping of the member 15, with the sill, the outer ends of the arms are turned inwardly toward each other and are arranged for biting engagement with the upper and lower faces of the sill. By this construction the member 15 is capable of gripping engagement with sills of different thicknesses, as will be readily understood.

In the operation of the device, the member 15 is properly clamped in engagement with the sill of the car to be moved, so that the pawl members will be disposed for engage ment with the ties of the railway. Then when the operating lever is moved for wardly toward the car the shorter pawl member 19 will engage with one of the ties and cause a forward movement of the car, and upon a rearward movement of the lever, the longer pawl member 18 will engage an other tie and cause a further forward movement of the car. While the lever is being moved either forwardly orbackwardly, one or the other of the pawl members is being advanced to engage with a tie in advance of the tie operated upon. Thus by working the lever back and forth the car will be advanced with a step-by-step movement but of such gradual character as to be practically continuous.

The device is particularly adapted for use in mines where motors or mules are not always available, and the miner or several of them must push the car to such a point as it can be hauled to the cage for dumping or raising to the surface. Thus one man can do the work himself.

What is claimed is:

A car pusher including a yoke member having the extremities of its arms turned inwardly for biting engagement with the draft sill of the oar, a bolt disposed vertically through the arms for forcing and holding the arms in such engagement with the sill, railway tie engaging arms, a block secured Within the bight portion of the yoke and having a horizontal pivot member dis posed therethrough, and a lever mounted for rocking movement on said pivot member and having the said arms pivotall'y 'e'on'nted thereto above and below the said pivot 10 member, respectively.

In testimony whereof, I affix my signature, in the presence of two witnesses.

FRANK F. STERNER.
